"You got paged too?" Meredith Grey frowned as her best friend and colleague Cristina Yang came to stand next to her on the hospital's tarmac. The tall, Asian surgeon resident nodded as she turned her friend around and pushed her straw blonde hair out of the way to tie the trauma gown in her back.

"We all got paged," General surgeon Miranda Bailey announced as she, Alex Karev and Lexi Grey joined him, their plastic gowns floating in the wind. The short, African American attending efficiently designated spots to everyone and they all obeyed without a second thought, helping each other fasten the plastic gowns and snapping surgical gloves on.

Lexi Grey, Meredith's younger half-sister, quickly pulled her long, dark chocolate locks into a pony tail before accepting a pair of gloves from Alex. The slightly shorter man rolled back and forth on his heels as he waited impatiently for the patients to arrive, only stopping when Bailey lifted an eye to stare him down. The blaring of the ambulances' sirens were getting closer informing them of their imminent arrival. "Anyone has any idea what we're expecting?"

"Dispatch said two people had crashed through a glass ceiling in a building in construction on the other side of town. Both are critical, a male and a female," Orthopaedic surgeon Callie Torres repeated what she had been told by minutes earlier, bracing herself for the likely broken bodies that would arrive soon enough. Taking example on Lexi, the tall, curvy Latina doctor pulled an elastic band from her pocket and pulled her wavy, black hair away from her face so the strong winds would stop pushing them into her eyes.

"A glass ceiling? Nasty," Cristina muttered gleefully as she imagined what kind of surgeries her upcoming patient would be requiring. "What kind of idiot would go and play around a construction site anyway?"

All frowned when multiple sirens could be heard, not only the ones coming from ambulances but from police cars as well. "What the hell?" Karev shot Meredith a curious look just as three police cars raced through the hospital parking, one ambulance making its way in a few seconds later, screeching to a halt before them.

"The idiot who decided to use a half built building for a game of hide-and-seek is the prime suspect in Manuela Donovan's murder." Bailey glared at Cristina, who took the hint and stepped back.

"The Governor's daughter? Sorry, I didn't know. Who's the other patient?"

The doors to the vehicle opened and two paramedics came out, interrupting Cristina, and promptly read out the patient's case to Karev and Torres. "Patient is a Caucasian male, early twenties, multiple fractures to the legs, ribs and possibly the spine, and deep lacerations when he fell through a glass ceiling. BPs are dropping and he flatlined twice on our way here. His throat is closed up so we couldn't intubate."

"Okay Karev, Little Grey, you're with me. He's bleeding out so we need to rush him to an OR stat," Torres ordered, her voice strong and steady until she noticed the cuffs on the patient's wrists. Her face darkened but she grabbed her side of the gurney while Karev took the other. No one said anything as two cops came to stand next to them to keep an eye on the criminal even though he was cuffed and unconscious. "Come on Grey, let's go!" Lexi swiftly but cautiously jumped on the gurney and resumed CPR while Jensen was rushed inside, leaving a trail of blood in its wake.

Bailey sighed as the other ambulance's tires squealed as it entered the tarmac and the remaining cops gathered closer. "The other patient is the cop who was trying to stop him."

Meredith and Cristina exchanged a somber look just as the doors to the second ambulance opened in a rush and a sharply dressed yet distressed man jumped down to give the paramedics more space to work. "What do we have, John?"

The paramedic glanced from Bailey to Castle and the cops and swallowed nervously. "Detective Katherine Beckett, 31, possible multiple fractures to the back and pelvis, and head trauma. The other patient took most of the fall but she still has multiple lacerations on her legs and hip. She was conscious on and off on our way here, her oxygen level is dropping quickly and she's tachycardic."

"Ok Grey, go page Shepherd and meet us in room 3." Bailey barked and turned sharply to Castle, who was lingering too close for her comfort. "Sir, I'm going to have to ask you to back up if you want us to help her."

"Maybe you'd be helping her better if you were actually moving her into room 3 instead of just barking orders!" Castle snapped at her as he fought his way in and followed the now fast moving gurney.

Cristina listened to the bickering as she applied pressure on a particularly deep cut on Kate's right hip when she snapped her head up and stared at Castle in shock. "You're him."

Castle barely acknowledged her before returning an angry glare at Bailey, who was now trying to push him out of the room. "Sir, I know it's hard but you can't be in there, you need to let us help her."

"Then will you let me talk?!" he shouted angrily, although he was much more terrified than angry at the moment. She had to be alright, this couldn't be happening all over again, or he wouldn't survive it. "She was shot in the chest six months ago and she's still recovering. Just, talk to her if she wakes up so she won't freak out."

Bailey nodded quickly and indicated for a nurse to take him in the attendings' lounge. The woman had recognized the man as well and there was no need to make him wait in the public waiting room. Things would get crazy enough when the accident made the six o' clock news. She offered Castle a small smile as she stepped back into the room. "We'll take care of her, sir, you have my word."

Without waiting to see if he was leaving or not Bailey entered the trauma room and let a nurse shut it behind her. "What do we got, Yang?"

"It's him, and it's her."

"What?"

"Richard Castle! The novelist? He wrote the Derrick Storm series, and the new Nikki Heat books."

"Huh. I knew his face was familiar," Bailey agreed distractedly, not letting know she had almost squealed when she saw him jump down the ambulance and instead let her hands move over the detective's bloody form. She had started cutting through the clothes when she and Cristina's eyes met as they realized something else. "Does that mean that...?"

Bailey nodded, impressed if not a little intimidated as she recognized the injured woman on the gurney for the first time. "I believe so. She is the infamous detective behind Nikki Heat."

"Wow."

"Yang."

"Yeah right, sorry." Both were efficiently assessing Beckett's injuries when Meredith came back, her running shoes squeaking on the cold ceramic floor. "Derek's on his way. How is she?"

"We just gave her two units of blood and she's going to need an MRI and scans before deciding if she needs surgery or not. The swelling in her left shoulder indicates that either her collarbone or scapula is fractured, she's got a couple of broken ribs and the breath sounds are shallow on the left side," Cristina detailed the injuries one by one as the cardiothoracic surgeon cut through the cop's bra and ran professional fingers down Kate's surgical scar.

"Other than that it's mostly cuts and lacerations. Surgeon did a good job." She commented as she mentally evaluated the previous damages done to her patient's heart. "The scar tissue is minimal and looks like she's had a chest tube in also. Try and use the exact same area if you need to put one in to minimize the scarring, I'm going to go page Sloan."

Meredith frowned and shifted her eyes from Cristina's departing form to her attending. "What does she mean? She's had surgery before?"

"Who's had surgery before?" Derek asked as he came in, his scrub cap already in place and a mask hanging from his neck.

"Detective Katherine Beckett," Bailey informed both doctors as she asked a nurse to give hand an intubation kit over. "Her partner said she was shot in the chest a few months ago. Her heart's holding fine so far but her left lung is about to collapse so Grey's going to intubate her now."

Meredith and Derek stared at each other, flashbacks coming back to the both of them. Derek had been shot in the chest last year when a grieving man, obsessed over his wife's death, came in the hospital armed and started shooting surgeons and other doctors, killing six and injuring another eleven.

Taking a deep breath, Meredith gently removed the breathing mask from Kate's face and proceeded to intubate her so her oxygen level would go back to normal. She listened to the breathing sounds when she was done and noted with satisfaction that the detective's vitals were going back up.

"Beckett? Richard Castle's muse?" Derek stared at his wife and Bailey in surprise, clearly not expecting this. "I guess it explains the cops out there...I thought she was a New York cop."

"She is but somehow she was working on the Governor's daughter's murder," Bailey began to say but her eyes jumped to the heart monitor when he started racing and Kate regained consciousness, her body thrashing against the restraints holding her in place. "Mrs. Beckett, it's alright, you need to try and calm down."

Bailey's voice had little effect on the detective so Derek moved into Kate's sight and moved his hands so one was on the woman's shoulder while the other held Kate's hand tightly. "Katherine, listen to me, okay? Don't fight the breathing tube or you will be in even more pain. Your lungs are too weak right now so just let the tube breathe for you, can you do that? That's it, just relax, let it do its job."

Derek was speaking calmly and smiled gently when agonizing and glassy sienna eyes locked on his. "That's it, you're doing good. That's it, just relax."

Kate struggled and tried to fight against the hands on her and especially against the tube running down her throat, feeling like it was trying to choke her to death from the inside. She forced herself to relax but the pain she was in made it hard to focus on anything but on the pair of blue eyes currently staring at her.

She heard a man's voice talking softly to her and her fuzzy mind clung to it like a lifeline, oddly thinking that it sounded like Castle. Her sight was blurry but she found herself staring at a pair of warm, blue eyes, which only added to her confusion. The man's hair, darker, longer and somewhat curly was what finally told her that Castle wasn't by her side anymore, sending her into another fit of panic.

The voice was still talking softly to her as she felt her eyelids growing heavier and her head began to spin viciously. She panicked against the unwelcome feeling but she knew there was no escaping it. As the drugs rapidly sent her into an artificial slumber, it was with a resigned sense of relief that she let herself succumbed to the darkness.
